Error while Generating wsdl from wsgen tool

Hi All,

I am trying out wsdl generation with the help of the wsgen tool. I have endorsed jaxb-api.jar and jaxws-api.jar files.

I have a library TestTo which has TestingTo class AS

public class TestingTo implements Serializable{
public String name;
}

This TestTO library is included in webservice project.

My WebService is as below-

@WebService()
public class IcfInfra {

@WebMethod(operationName = "printTest")
public TestingTo printTest(@WebParam(name = "string") String string)
{
TestingTo to = new TestingTo();
to.name = string;
System.out.println(string);
return to;
}
}

When I run Ant script for Wsgen I get following error -

main: [exec] Note: ap round: 1 [exec] Problem encountered during annotation processing; [exec] see stacktrace below for more information. [exec] java.lang.NullPointerException [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalType(WebServiceVisitor.java:794) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalMethod(WebServiceVisitor.java:642) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.methodsAreLegal(WebServiceVisitor.java:611) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.isLegalImplementation(WebServiceVisitor.java:529) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.shouldProcessWebService(WebServiceVisitor.java:332) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceVisit or.visitClassDeclaration(WebServiceVisitor.java:123) [exec] at com.sun.tools.apt.mirror.declaration.ClassDeclarationImpl.acc ept(ClassDeclarationImpl.java:95) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceAP.bu ildModel(WebServiceAP.java:329) [exec] at com.sun.tools.ws.processor.modeler.annotation.WebServiceAP.pr ocess(WebServiceAP.java:270) [exec] at com.sun.mirror.apt.AnnotationProcessors$CompositeAnnotationPr ocessor.process(AnnotationProcessors.java:60) [exec] at com.sun.tools.apt.comp.Apt.main(Apt.java:454) [exec] at com.sun.tools.apt.main.JavaCompiler.compile(JavaCompiler.java :258) [exec] at com.sun.tools.apt.main.Main.compile(Main.java:1102) [exec] at com.sun.tools.apt.main.Main.compile(Main.java:964) [exec] at com.sun.tools.apt.Main.processing(Main.java:95) [exec] at com.sun.tools.apt.Main.process(Main.java:85) [exec] at com.sun.tools.apt.Main.process(Main.java:67) [exec] at com.sun.tools.ws.wscompile.WsgenTool.buildModel(WsgenTool.jav a:219) [exec] at com.sun.tools.ws.wscompile.WsgenTool.run(WsgenTool.java:123) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAcces sorImpl.java:39) [exec] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMet hodAccessorImpl.java:25) [exec] at java.lang.reflect.Method.invoke(Method.java:597) [exec] at com.sun.tools.ws.Invoker.invoke(Invoker.java:131) [exec] at com.sun.tools.ws.WsGen.main(WsGen.java:52) [exec] error: compilation failed, errors should have been reported [exec] Result: 1

Now I modified my webservice as

@WebService()
@XmlSeeAlso({
TestingTo.class
})
public class IcfInfra {

@WebMethod(operationName = "printTest")
public TestingTo printTest(@WebParam(name = "string") String string){
TestingTo to = new TestingTo();
to.name = string;
System.out.println(string);
return to;
}
}

When I execute ant script i get error as -

main: [exec] Exception in thread "main" java.lang.ArrayStoreException: sun.reflec t.annotation.TypeNotPresentExceptionProxy [exec] at sun.reflect.annotation.AnnotationParser.parseClassArray(Annot ationParser.java:653) [exec] at sun.reflect.annotation.AnnotationParser.parseArray(Annotation Parser.java:460) [exec] at sun.reflect.annotation.AnnotationParser.parseMemberValue(Anno tationParser.java:286) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotation(Annot ationParser.java:222) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotations2(Ann otationParser.java:69) [exec] at sun.reflect.annotation.AnnotationParser.parseAnnotations(Anno tationParser.java:52) [exec] at java.lang.Class.initAnnotationsIfNecessary(Class.java:3070) [exec] at java.lang.Class.getAnnotation(Class.java:3029) [exec] at com.sun.tools.ws.wscompile.WsgenOptions.validateEndpointClass (WsgenOptions.java:244) [exec] at com.sun.tools.ws.wscompile.WsgenOptions.validate(WsgenOptions .java:226) [exec] at com.sun.tools.ws.wscompile.WsgenTool.run(WsgenTool.java:122) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [exec] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAcces sorImpl.java:39) [exec] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMet hodAccessorImpl.java:25) [exec] at java.lang.reflect.Method.invoke(Method.java:597) [exec] at com.sun.tools.ws.Invoker.invoke(Invoker.java:131) [exec] at com.sun.tools.ws.WsGen.main(WsGen.java:52)

Appreciate If someone can let me know what needs to be done in order to sucessfully generate the wsdl.

Thanks, Adish
